Metric Chronetic Theory Phase 7: Empirical Convergence and 19.41 Invariant Dynamics in Non-Dissipative Metric Media

Metric Chronetic Theory (MCT) Phase 7: Metric Impedance & Cosmological Validation advances the development of MCT by introducing and formalizing the concept of metric impedance as a chronetic property of structured vacuum media. This phase investigates how chronetic dynamics propagate through lattice‑constrained space‑time and evaluates whether metric impedance provides a measurable bridge between local chronetic behavior and large‑scale cosmological observations. The project explores predicted signatures, validation pathways, and cross‑scale consistency tests that connect the MCT framework to empirical astrophysical and cosmological data. Phase 7 builds on earlier phases by shifting from theoretical construction and hardware specification toward model evaluation, observational alignment, and the identification of falsifiable predictions. The accompanying preprint contains the full technical development, derivations, and proposed validation strategies.
